Automatic Train Control

[nw-mailing-list at nwhs.org]

In the April 1926 issue of the N&W magazine, there is an article
describing the installation of the ATC for the Shennandoah Division on
the Class J 4-4-2's . 

 

Other handy sources for descriptions of ATC devices are Locomotive
Cyclopedias, especially, the ones from the 1920's and early 1930's.

Gordon,

 

    I have no knowledge of the steam locomotives equipped with the train
control.  However, when I first started with N&W in 1963 as an
apprentice electrician, I remember testing a couple of the "Redbird"
passenger diesels that had what was called "automatic train control".
We used what looked like  tuning forks to activate a device under the
brake rigging and it would initiate a penalty application of the train
brakes if not acknowledged.  The train control equipment was located on
the long hood right side just in front of the cab window at the end of
the walkway and outside the carbody door that opened to the generator.
I was never told where they were used.  Were these units used on the
"Cannonball" to Richmond?
